TO ALL WHOM Il MAY- CONGERN: l

I Be it known that I, MOSES P. FARNHAM, of Rock county, and vState of Wisconsin, have invented a new and useful Improvement in a Supplemental Fire-Box for Stoves and Furnaces; and I do declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the' letters' of reference marked thereon.

The nature of my invention consists in making a movable orV supplemental re-box, of peculiar construction, to set inside a stove tire-box, and into the spacein the top of a stove-plate, in place of a boiler, and suspending it by a ilanch around its upper and'outer edge, and having a movable lbottom or grate that'may be raised to different points of bearing to bring the fire nearer to or more distant from the articles to be cooked, or for other purposes; which grate rests on bearings, and may be tilted lor tipped edgewise sulliciently to preoipitate ashes, coals, dac., from its surface when desired; which general arrangement saves a great amount of fuel, and also avoids heating'the stove and rooms'wh'ere the stove is located. i

The same let-ters in each figure represent the samepart in the accompanying drawings.

Figure 1 is a, View of the .rebox,cut vertically, showing a series ot bearings, on which the lower grate sets at'diii'erent points; also the upper grate above the flue', andvthe'manner of its suspension inside the re-box.

Figure 2 is a top view ofthe grate, with the pivots or axes that rest on the bearings, shown in figs. 1 and 3,

Figure 3 is a ire-box, broken away, showing the bearings for the pivots; also a grate tilted edgewise, to

dump the ashes, cinders, coal, 86o., intothe stove below.

Figure 4 is a top view of a lne grate shown 'in iig. I, and prevents the smoke from coming into a room lwhen articles are removed from the top of the fire-box.

Figure 5 is a hook by which to move the grate.

A., in figs. 1, 2, and 3, ismysupplemental fire-box, while B B B, in figs. l, 2, and 3, serve as bearings for the axes a a a oi' the grate,rthe grate having a'loop orl'aperture, D', for the hook F, fig. 5, by which the grate is handled in placing it`on the different bearings, as needed in bringing the re of coal or other combustible material nearerto the articles to be cooked or heated. Also the grate-has three axes a a'a, and corresponding sets of bearings.l The bearings for the a'Xes are notvnecessarily placed equidistant, it being. better to place two of them apart, as a to a', in g. 2, which allows the grate' to be tipped or tilted, as shown iu iig. 3, whichY precipitates asli'es or refuse matter into theire-box of the stove. The ilanch la, figs. 1 and 3, rests on the stoveplate, and keeps the supplementalv {ire-box from dropping into the tire-box lproper oil-'the stove, while the hook e c c, attached to the ne hre-grate E, serves to support this grate above there and above the flue G; and the slide H-scrvos to close the ilue wholly or in part, as may be desirable. i

My supplemental fire-box, suspended inside a stoveor furnace firebox, is light, Vcheap of construction, and rge percentage of fuel, and heats apartments in which a stove or furnace is located but a small degree saves a la Snc., in an ordinary stove, which is important in hot weather, and can be used compared with a fire for cooking, for most oi' the ordinary domestic purposes.

What I claim as my invention, and desire to secure by LettersI Patent, is I I. The supplemental {ire-box A, for stoves and furnaces, having a movable bottom or grate, D, that may be'placed on different bearings B, substantially as and for the purposes described.

2. The general arrangement of a supplementalv stove vfire-box, with grate D, bearings B, lue line grate E, when the whole are constructed and arranged substantially as and for the purposes described.
